BOX CONSTRUCTION.

Application filed August 3, 1918.

To all whom it may concern:

Be it known that I, JAMES R. PEARSALL, a citizen of the United States, residing at Rochester, in the county offMonroe and State of New York, have invented a new and Improved Box Construction, of which the following is a specification. r

This invention relates to boxes or other receptacles made of sheet metal and because of its construction has especial reference to those of the knock-down or collapsible type although it is not intended to be used as such.

One of the objects of my present invention is the construction of a strong and rig-1d box having separable side walls, end walls, a top.

and a bottom all formed of sheet metal and engaging each other in such manner that, when assembled, no fastening devices of any nature whatsoever are required.

Another object of the invention is the construction of a box of the character just above described adaptable for use as a toy bank and in which the six sides are exactly similar with the exception that one of them is pro- Y vided with an opening for the reception and permitting removal of the coins.

A further object of the invention is the construction of a non-collapsible box,-yet

formed of separable members and without Th fastening devices,with protecting beads or rolls along all of the edges for their entire length and with such rolls cooperatingly engaging the walls of the box to hold them firmly in place.

And, a final object of the invention, when a box constructed in accordance therewith is intended for use as a toy bank, is to provide a removable cover plate for an opening in one of the walls thereof and held to place in such manner as to have the appearance of being permanently secured, such plate having a coin slot therein and the opening which the plate covers being for the purpose of permitting the removal of coins from the bank.

The accompanying drawings illustrating the invention as embodied in a box adapt able for use as a toy bank are as follows Figure 1 is a plan view of one of the side walls;

Fig. 2 is a plan view of the top wall;

Fig. 3 is a sectional view taken on the line 3-3 of Fig. 1;

Fig. 4 is a sectional view of the top wall taken on the line 4-4 of Fig. 6;

Fig. 5 shows the box as viewed from the with respect to- Fig. 6;

F g. 6 is a top plan view of the box;

Fig. 7 on the line 77 of Fig. 5,

And, Fig. 8 is a side view of the box with parts broken away to show the tion of the several walls just prior to springmg the last one to place.

Similar reference numerals refer to similar parts throughout the several views.

I The box comprises side walls 1, 2, 3 and 4, a bottom 5 and a top 6. These several wall members are similar in that they are formed, as in Figs. 1 and 3, withparallel extending rolls or beads along two edges, which I will term the ends, while adjacent these side edges for the purpose of reinforcing the wall body are paral- Y lel extending outwardly pressed corrugations 7. The end rolls are formed with their centersvin substantially-the same plane as the wall body and preferably extend the entire distance between the side edges. The size that a box is to be of course determines the length and width of the several members, but in this instance the box is square and all such members are consequently of like dimensions and are formed by the same dies. e top 6, however, has a centrally disposed aperture 8 for the purpose hereinafter to be explained;

In order that the drawings may be more readily understood, I will designate the rolls for the side walls 1, 2, 3 and 4 by the numerals 9, 10, 11 and 12, respectively, those for the bottom 5 by the numeral 13 and those for the top 6 by the numeral 14.

The box is assembled by first setting up one at a time the bottom 5 and the four side walls 1, 2, 3 and 4, the relative positions of such members being such that a side edge of one member will engage a rolled end of an adjacent member which arrangement brings the rolled ends of two opposite side walls in planes at right angles to those of the two oppositely positioned side walls. The top 6 is then placed by engaging one side edge thereof along and under the top roll of one of the side walls, in the manner shown in Fig. 8, and springing it into place so that the opposite side edge will similarly engage the top roll of the corresponding 0pposite side wall. This is accomplished by means of a suitable tool, not shown, having projecting members adapted to engage in relative posiand with parallel side edges,

the opposite ends of the roll 10, see Fig. 8, whereby the side wall 2 may be drawn outwardly and the parts sufficiently sprung to permit the top being forced to place. The rolls are preferably each formed with a free edge so as to yieldingly engage their respective cooperating side walls, the rolls thus forming yielding abutments to hold the walls in engagement against looseness.

When the parts are thus assembled the result is a box rigid and strong in construction with the four side edges provided with vertically extending rolls or beads and with similar rolls extending horizontally along all of the top and bottom edges, such rolls yieldingly engaging the several wall members to firmly hold them in place. The side edges of each memberengage, it will be noticed, corresponding rolls of two adjacent members. In the assembly of the parts, when all are similar as inthe stance, it is of course immaterial which constitutes the bottom or the sides and it is also immaterial whether it is the bottom, top or one of the sides that is the final member to be positioned and the one that has to be sprung into place.

As above stated, the top 6 has an aperture 8 for permitting the coins within the box or bank to be removed and this aperture is normally closed by means of a removable cover plate 15 having a coin slot 16 therein. This cover plate is provided near its ends with rivets 17 and 18 headed on both ends and adapted to form locking engagement with the top wall 6 by one of them engaging in the short slot 19 at one end of the aperture Send the other in the elongated slot 20 at the other end of such aperture near its forward" end. In order to remove the present incover plate it is moved longitudinally so as to disengage the rivets 17 from the short slot 19, after which it is swung to one side or the other, as indicated in dotted lines in Fig. 6 at 21, and then slightly raised and drawn forward to disengage the rivet 18 from the elongated slot 20. The cover plate has the appearance of being permanently secured to ace.

While I have shown and described a box as particularly adaptable for use as a toy bank it will of course readily be understood that it is within the scope of the invention to construct boxes for other purposes and of various sizes.

What I claim is:

1. A box construction having six rectangular walls, each of which has plain op posite side edges and resilient abutments along the other two sides, the resilient abutments of each wall exerting a pressure on the outer faces of two opposite walls of the box to hold said walls against the opposite gdges of still two other opposite walls of the 2. A box construction having six rectangular walls each of which is formed from sheet metal and has two plain opposite sides and two rolled opposite edges, the free edge of the metal in each roll being on the inner side of the roll, each of said walls at its rolled edges abutting the straight edges of two other walls and having the free edges of the rolls resiliently engaging the outer faces of said two walls and its plain edges lying against the inner faces of two other walls with the free edge of the roll of each of said walls resiliently engaging its outer face.
